Why does SpaceX keep changing the BFR? The evolution of BFR
Vložit
- čas přidán 19. 09. 2018
- Elon Musk updated the world with the plans for SpaceX's BFR at SpaceX HQ in Hawthorne. I attended to learn about all the new exciting changes! For now, we're going to just look at what has changed with the vehicle over the years and why it keeps changing. Later we'll do more in depth videos about Yusaku Maezawa's beautiful #dearmoon project and the weird reentry system of the new BFR!

Once more thank you for being the only one with a contributing question. And not just asking in 10 different ways how much Yusaku Maezawa paid
Exactly!!
Very true
Just highlights again the click-baity nature of news reporting, $$$ make the headlines unfortunately. Tim rose above all that nasty business!
This!
That last one was a little funny...asking for a percentage, l Iike they could sneak that past them and not know that Elon and MZ wouldn't know they could do the math
hey tim, when you asked elon about the question he seemed like his expression brighten cuz everyone else was talking about things that i think elon is bored about, so you probably did something good for his mentality a bit.
BLUE asian I saw that too... good 👂
Noticed it too, he lights up a lot when he hears the question because it is about the design and technology/engineering instead of the boring stuff like "but how much money is he paying you to do this?". Those type of questions are clearly not what Elon are looking for at these events(hint hint: Tesla stockholder conference calls). Elon Musk enjoys talking about the engineering of it all but most people do not have the mind to grasp that stuff so he rarely get to talk about it in Q&A's.
he also lights up when he calls people child rapists
Sean Bean
Stimor, and then Wins the Lawsuit!!!
Thanks for focusing so much on the designs, and Cool to see Elon reacting so good when you asked that question!
When world's collide.
Make a replica of the marble machine and send it to mars😀
Well, what brings you here?!!
@@deadliner178 engineering obvs. Wintergatan is music engr
Woah u r here epic!
Tim asking the best question at the event. Seemed like the only one Elon was interested in! Good work!
Ya I thought that was great, and thought way to go, mate!
Elon said to tim that he love talking to him
So how much longer before Elon offers Tim a role as PR / Education manager for every stream etc etc. I mean, having Tim in the live stream explaining what they are doing for every launch and explain the design changes and so on. You really want a guy that loves talk about his passion. Of course, best would be Elon on every stream and be technical to the deep end. But he has enough on his plate for sure! Upvote for the idea as Tim for a possible PR manager/face for streams and such!
Tim, being good at CZcams, MIGHT make more money than Elon could offer him
@@poopscoopproductions3177 he probably won't make more money with CZcams until he gets at least 5 million subs. Which let's be honest he deserves it with all the high quality content

Hahaha yes! I noticed that too!!!
Yeah true

Oh wow this is very old
@@AidenHere Thanks for reminding me of this lmao
The fact that SpaceX is giving so much insight into their design decisions is (at least to me) another proof, that the main objective of Elon is just to move mankind forward and actively encouraging other companies to join the space race, while at the same time he has a huge amount of faith in his team that, at the end of the day, they will come out on top.
It has been so cool when you got to ask that question, thank you so much Tim. Greetings from Argentina!
Cuantas copas tenes?
Less cool that he didn't get an answer...
¿Para beber? Soy estudiante de ingeniería, no me dan copas por aprobar materias (lamentablemente ☹️). ¿Vos que haces?
He did get an answer...
Okay, not in the video he didn't, is there a way I can actually hear the answer?
Hey Tim,
Great job on this video! We were all proud of you when you asked Elon a question!
Yeah I was sorta getting bored with the "hOw MUch Is He PAYing" questions, when I heard Tim speak I was super excited, I kinda felt happy for him, amazing how far he has come, a 1 on 1 q&a session with elon would be great!

The moment i heard you asking your question live I couldn't believe it. He even complimented you, that was my favorite part!
In Australian parlance, you are a deadset legend! That question to Musk was devastating. Bloody great work!
I would like to honestly say thank you for this channel, all the news these days it so negitive, but this channel manages to find some posistive news that gives me a little hope in humanity.
Agreed... Definitely need some positive news
The world is even crazier now. I'm so happy I found this channel.
I just realized- This is the first real rocket to actually land on its fins like they always do in SciFi :D
Who knew TinTin, Wallace and Gromit, and Abbott and Costello had it right
And Werner Von Braun!
Von Braun was an absolute legend.
Is just another hint that Time Travel will happen in 2036.
Jeff Vader - He was a nazi but ok. In terms of rockets, yes. Otherwise a big douche.
Tim, when you asked one of the only meaningful questions in the BFR conference the other day - I just want you to know (from the comfort of my couch) I gave you a virtual nerd fist bump. Good God, why do they let some of those reporters in there?!!?!? Who the hell cares how much he paid?! Tell us about the design changes! tell us about how you have managed to achieve 300 bar/higher! Either way; Another great video, man!
Definitely, re: virtual nerd fist bump. Clearly Elon felt the same way; he instantly brightened up and answered it enthusiastically.
Re: very poor average quality of questions - this is particularly bad with US-based media I find (I mean, surely I'm not the only one that noticed a difference between the US and Japanese reporters there, right?). Completely obsessed with money. It's like they use it as a proxy for respect/importance/power. Maybe they really do 😫 I'm not sure. And it's not like it's all the media's fault; if there wasn't a market for that "content", they wouldn't produce it. Clearly the consumers value it more than quality reporting. Man, that's depressing.
(For an extremely clear picture of this, look at election media from the US versus other countries. It's dramatically different. Much less emphasis on spending and other money-related matters, fewer soundbites, more detailed reporting)
LagLawyer Well actually quite a few people care about how much she paid. It’s only natural.

If you ever sit down with Elon Musk ask him only the technical questions. We're all nerds behind the screen remember?
Not just technical, some of us are interested in the design philosophy behind it too!

Elon: "A Good Eye"
Omg the lord has spoken to me.
8:57 I didn't even notice that you have different eyes colors until now hahaha
@ 8:34, the grin on Elon's face showed how happy he was when he got a cool question to be answered
Why did they keep changing the Falcon 9?... it needed perfecting! The closer to production the more issues are discovered with any design, which need to be solved.
Also, there's so much talk about "Elon Time", and SpaceX delays... but no comments about SLS, James Web and any number of other projects that are also delayed way more than SpaceX. Space is hard people!
There are lots of talk about SLS, Webb and so on, but they are a completely different type of project. The SLS design has been frozen for a long time, but still hasn't flown. With that in mind, it's quite puzzling that they are still making such major design changes to BFR, a launch vehicle which is supposedly going to fly in less than 4 years. Personally, I think the BFR stack will probably get major delays, and NASA's EM-1 and EM-2 will probably overtake it.
If it flies and keeps the performance now promised (the payload to LEO dropped from 150 to 100 tons from 2017) it will still be an impressive vehicle. I just hope it will be used for more than shooting artists into space.
Not to dis NASA or it's hardworking engineers but SLS is a complete joke. It's just a newer Saturn 5 with an insane 1 billion dollar price tag per launch with zero reusability. NASA should focus on science exploration like rovers and the james webb and leave the rocket building to companies like SpaceX.
‘Rocket time’ is pretty much the same deal as ‘Elon time’: ever the optimistic.
Media :(
1. SLS isn't a Saturn V. It is a new design based on existing Shuttle and Delta IV components. Reusability doesn't matter when you are only doing a few launches a year. But I agree, the biggest problem with SLS is the cost, which is partly because Congress have forced NASA to adapt a compromised design focused more on keeping jobs than actually making a launch vehicle (which is mainly the secondary purpose, sadly.) But it is probably going to work just fine due to it's conservative design, and will still be the most powerful rocket in the world when it flies.

That still cracks me up.
TBH I sub'd ages ago but I didn't take you very serious w/ the jumpsuit thing, and figured you must have a (hmmm...) more 'grade school' target demographic. I figure I should stop by and reassess my assumptions after the respectable question that went over my head during an international Space X press conference. I think I may have mixed up my wires here. Nice set, nice upload, nice job. I guess I've been missing out on some good content. This is worth seeking out on the sub feed at a minimum ;)
Thx for the wake up call.

Woah! Thank you!!! That means so much!!! To be honest I try and produce content for everyone but really do want to focus on family friendly. But that means a lot. I do take it all very seriously, so thank you for re-evaluating!!!

By the way I learned of you by watching the live stream and you could tell Elon appreciated it. You have a new sub bro. Thanks for making space great dude.
Everyday Astronaut for #Dearmoon. Who's with me? I mean, he's got space knowledge, he's a vlogger/filmmaker, he makes music, AND he's talked about spacex for years. The creative works he'd make after (or during) the Dearmoon mission would be amazing.
Yeah we need to send tim dodd to the moon
& photographer
But we need to bring him back safely too 😃
LETS DO IT
Tim Dodd, the actual astronaut
Love the rundown! A few interesting things:
- Elon mentioned that the AFT cargo bays can be switched for vacuum engines. This means that SpaceX can focus on streamlining the BFR without having to design it from scratch later. Vacuum engines are good for increasing mass to orbit, so they probably figured out that 100 tons are good enough at first. When the vacuum engines are switched in, we will see far more than a "mere" 100 ton LEO launch capability.
- The AFT cargo bays are great for storing Starlink satellites. This means that SpaceX can run launches for customers while sending their own satellites up AT THE SAME TIME! Again, they probably don't need vacuum engines to do this, so it's a really clever solution.
- Considering the points above, we will probably see two (or more?) versions of BFR in the future: A version with sea level engines only and a vacuum version. The sea level version will be great for Starlink/light duty delivery and personnel delivery/tourism; especially point-to-point flights on Earth. The main BFS could carry passengers, while AFT cargo could carry trade-goods. The vacuum version will be great for heavy duty hauls (like new space stations) and long hauls to other places in the solar system.
can't wait for that kind of flight to be reality... maybe even in the style of the Expanse universe... shuttle from port Lunar base bigger ship (presume BFR) transit to planetary bodies or stations...
I think Tim is right that the designers and engineers have sacrificed payload capacity for payload _volume_. The Raptors are now more powerful than they were for the 2017 design so I suspect that if the '2018' Raptors were put on the 2017 BFS that payload capacity may well exceed 150t, but now that the BFS has more and larger stabilisers and more payload volume, it means the capacity has dropped because the dry weight is higher.
It also means, as you said, SpaceX can focus on getting the BFR operational on one engine design and come back later to optimise it. Tanker BFS's will probably retain the sea-level engines, while cargo and crew BFS's will shift to a mixed set.
SpaceX is also clearly targeting the BFS to service NASA's plans for both the (ill-advised) LOP-G and Lunar services in general. The mental image of a BFS with 1000m^3 of habitable space docking with the LOP-G with ~125m^3 of habitable space amuses me greatly.
I don't even wanna know what that thing (the LOP-G) is gonna cost riding on the biggest Pork Barrel ever created
"Why not stick on a hyper-drive, or a worm-hole engine, or an anti-matter warp drive while you're at it?"
Probably because unlike rocket engines (both 'sea level' and vacuum), carbon fibre composites, radar guidance, computer-control, and hydraulics, those don't exist.
"You fanboys are a hoot. Zero, and I mean zero scientific understanding, and close to zero common sense."
We know that rockets work. We know that SpaceX's F9 rockets in particular work. The BFR is fundamentally a problem of scale.
"a blatant con-man as Musk"
Oh, there it is.
TheOneWhoMightBe Lol. That last part is so true. Elon’s haters all try to use science to defend themselves but it’s all just a screen to hide that their entire basis for hating Elon is a personal issue, not an objective one.
Nice channel! You showed up in recommended probably from watching other SpaceX videos and I thought it was really cool that you were the one who asked the only REAL question! Liked & subscribed!
The good eye pun made me spill my coffe ;) Cheers TIM, Love Your work!
Same. I literally Laughed. Out. Loud...
Not a pun but still funny
You got to speak to musk! Good eye!

Yeah me neither. He said it and i paused just to make sure and now he's cooler than ever!!!!
Same here, I had no idea!

Great video Tim! I finally gave in and jumped on Patreon. The quality of your videos, the info you provide and how much I look forward to your content; I just couldn't excuse myself anymore for not helping you out in some small way. I'm actually planning to be at the SAOCOM 1A launch this coming October. If you're gonna be there, let us know so we can stop by to say hi. Keep up the great work!
Thank you so much! That truly means a lot!!!
Thanks for giving lay people a peek into the engineering feats of space travel. Your enthusiasm is infectious!
I think the 2016 ITS looks the coolest; it's got this weird sci-fi aesthetic.
Nah man, it's not sweaty and shiny enough.
Exactly
You can tell it’s designed by space-x, the new ones are mostly designed by nasa.
@@psych5581 the latest BFR looks ugly compared to the first concept
Yeah, but that's how you know the latest ones were designed by actual engineers, and not concept artists.
Tim, you are the best! Thanks for your job and hi from Ukraine!
and me!
I like how the new BFR kinda looks like the Spaceship from Futurama. :D
As always Tim, great Video!
Whooaaaa if you never said that you had different colored eyes, I dont think I ever would have noticed. Super cool though. Thanks for the great question to Elon and thanks for your videos!
Really love this channel Tim, I love how it just keeps getting better, great content, edits shooting is really top notch. From one completely unrelated channel to another, I genuinely love your authenticity and connection with the audience. Well done mate
I am impressed, you have gone from a bit silly (in a positive way) youtube space show, to be one of the premie space journalist, you should try to interview Jeff Bezos next ;)
Exciting things happening in the spaceflight industry
Finally.
Exciting things happening space flight, war going on in Asia, crazyness on college campuses, it's the 1960s all over again!
only because SpaceX!!
You're literally the best in this business, Tim. I am an extreme fan of yours and TMRO's. Bid you good luck to bring up more exciting stuff in future. And my God, that studio's amazing!
Great vid, Tim! My wife and I laughed out loud at the "good eye" part. I am very happy you are there to help all of us non engineers get some great answers to questions.
I love everything about this channel from the content to the Hi-res video quality. Amazing work!

been trying to find a channel that highlights everything space related. awesome to stumble upon your channel! love the videos so far! thank you for the creativity and information
I wish Elon Musk would have addressed your question about the launch abort system.
Bradley Graham he had to keep to his script... the guy is a frontman
its bad commercial to talk about failures
There will almost certainly not be a launch abort system.
Well done Tim - Double Win!
Best live question
Best post summary
Awesome videos. I love pretty much EVERYTHING space!!
hey tim, I saw you live when the spacex conference aired and felt like we all were there with you asking elon and maezawa questions. thank you for your work, I think that you will be rewarded in the long term, like traveling to space in significant missions and so on (I know you will think this is probably not gonna happen but I believe it certainly will. Keep doing your magic and thanks for everything. big hug from andalusia
I have a theory on why the 7 sea level raptors on BFS: It‘s for testing reasons so it can launch all on it‘s own with a high fuel load and do the high altitude hypersonic TestFlights Elon talked about without requiring the booster to get it there.
Human Person: I never thought of that! Good catch.
Good theory!
he said that they will develop vacuum engines too which will increase the payload capability to mars by a lot (this should the capability for LEO aswell) I hope they willl push this configuration sooner than later after initial suborbital testing is done, no vacuum engins for an upper stage is pretty senseless
It is so frustrating how during the press event the most common question was about cost. Here are 2 visionary men, one who is taking on the task of making us a multi-planetary species and making us dream about space, the other one is risking his life for this voyage. How awe-inspiring isn't that ? I got goosebumps, but only thing the mainstream press is asking about is cost and money. WHO CARES WHAT HE PAID???? the man is going to the ACTUAL MOON, fulfilling his and others dreams. Of all the hundreds if not thoushands of possible questions they are wasting the time asking about cost like 4 times ?! WHAAAAT THE HEEELLL. What happened to inspiring people to dream about a better tomorrow ??
@@javaman4584 Typically reporters don't subscribe to Socialist/Communist ideology. It's bad for business. You're making a false equivalence.
And most people don't have the knowlege of Space flight and its history to understand that even if this isn't immediately impactful for the common man, the long term results from this will inspire more people to get into STEM which directly benefits everyone.
I understand where they are coming from, but as is unfortunately often the case, they simply don't know what they're talking about in regards to this subject. Which is quite normal for average people. Hopefully #Dearmoon can help to change that.
But it in no way means that their underlying philosophy is faulty. Helping those in lower income brackets also majorly contributes to STEM by raising peoples abilities to pursue their interests.
Harambe's Ghost - The reporters are smart, smart enough to know they need to appeal to those of way-below-average intelligence
@@javaman4584 WTF, no. They're making offerings to the all-pervasive US religion of money. They're trying to figure out how important the guy is, by means of the cost he paid - it's a proxy value for respect deserved, in the religion.
Because vision gets you to the moon. Cost/benefit lets you stay on the moon.
Vision lets your space program survive 1 or 2 mission where everyone dies in a space accident (Space exploration is dangerous). Cost/profit allows your space program to survive when 14% of the mission result in death.
Martin Lööf the shareholders, don’t be silly price is a very important question
Love how you covered the subject from every angle... just subscribe :)
Imo your best piece yet.
The engineering process discussions are some of my favorite items!
Hi Tim @Everyday Astronaut
Important to note: the fins give drag, but not much compared to the hull. Their real purpose is stabilization and maneouvering. Just as Elon said, it's like a skydiver (very good comparison). Moving them "upwards" or to the "vertical" (rearwards in direction of flight), makes them give less drag and provide natural static stability on roll axis.
If the vehicle rollsto a side, that side's fin and cannard get more perpendicular to airflow, having more drag and making the vessel roll back to 0.
For pitching up, cannards can be put more horizontally and/or rear fins more vertically to make the nose more draggy than the tail, the opposite for pitching down.
For yawing, left cannard and right fin can be moved opposite to right cannard and left fin, deflecting air more to one side than to the other.
Also, all four surfaces can be moved to provide more or less drag and control the downrange distance.
It's a neat flight control system that can perform all those corrections without using RCS. It's awesome!
Thanks for asking Elon a technical question among the typical reporters' questions. By the way, if I asked about the money... I don't care at all about how much did he pay! I prefer to know how much will I need to pay, ho knows... 15 or 20 years from now?
Regards.
Tim, honestly I believe you can over qualify for an awesome job at SpaceX. Thank you for your inspiring insights
Love your channel and the technical and historical focus of it. Like you, I crave BFR/starship details as they emerge. I’m sure I’m not the only person that would enjoy more BFR content, even if it’s just discussing current reddit theories and potential tech hurdles! Looking forward to the next one

Just wanted to say that "The Scale Of It All" is a great track, and that I had no idea that you made music as well as being an amazing science communicator. Great work!
Fantastic video! I The moment I heard your voice in the Q&A I trow my hands in the air and shouted "YES!". It was that exciting. It also convinced me to support you Patreon.
One thing to note: in 10:07 you compare the SL Isp of SL Raptor with the Vacuum Isp of Vacuum Raptor. Which is not a valid comparison.
I noticed that sneaky audio correction at @6:48 XD
how much did your space ship/studio cost? :) seriously though. it was sad to see those reporters make fools of themselves that night
Like ever, that's the very reason the man himself proposed Pravduh, duh
Probably greenscreened.
Very impressed by your analysis, thank you.

One of your best videos from the “science communicator” standpoint. Well done sir!
Really well made and super interesting
You are kind of a musician right?
Go ask Yusaku if you can fly with him to the moon!
not kind of. he IS.
but he would be too old to fly (theory age by then, 40-50s) my guess of the theoretical max age for space is bout 20-30s
AsHalt - John Glenn was 77 when he went back up on the shuttle in 1998. As long as you can pass the physical and do the training, there's no "maximum" age. en.wikipedia.org/wiki/John_Glenn#Return_to_space
Gibson99dotcom
Ummm, there's no age limit on a government vehicle when you also happen to be a US Senator.
Let's go Tim!! Can't wait for that Reddit Q&A ft. Elon
One thing you forgot to mention about SpaceX sharing the design process... It generates excitement, curiosity, and the dreams that I felt growing up in the 80's watching the Space Shuttle. Elon is inspiring a new generation of scientists by bringing the public into his world. This can not be understated. Until SpaceX came along, I can not recall a single child I work with in school talk about space. Now, children are sharing CZcams videos and being excited. Inspiring a new generation is just as equal of an achievement. You earned my Sub! Godspeed my friend!
1:55 The foreshadowing is absolute perfection. Congrats on your trip to the moon, Tim!
Well done Tim. Best of luck getting that interview with Elon! He has a fondness for “today’s” media, CZcams, so you have that going for you!
Bring a baggie of weed, and youre in...
or a nice bottle of whiskey? I suppose people like nice things! who woulda thought, huh?
Who likes the old version better? My self I prefer the newer one...
I'll vote for any rocket that looks like Destination Moon/Tintin/A Grand Day Out.
I like myself
2016 ITS looked the best imo
It's not about look. But when you ask like that: The new one is ugly, the first one is epic
I refer the oldest look
so fantastic work, we support, it grows!
You are extremely good at what you do. Thanks for everything.
People let's flood Elon's Twitter account asking him for an interview with Tim #dearmoon #TiminSuit
I never noticed his eyes up until now. Wow.
Love your vid's man. Keep it up
Mah boi!
He made one of the questions we needed answered.
Excellent content, as usual.
2nd design was my favorite.
I came up with Elon's follow up to the BFR
Take three BFR, and put them side by side like the Falcon Heavy. Then put a full BFR on the center core.
The Stupid Falcon Rocket
or you can attach falcon 9 boosters to the side to aid in extra bigger payload
BFR Heavy
@@squdardt.9719 😂😂😂
great job on this vid. Very fun and informative.
Fantastic video..... thanks for posting
Can you make a table with all the spec comparisons?
The idea is to see how the BFR evolved, specification wise.
- Total height
- Booster height
- Spaceship height
- thrust
- number of engines
- cargo capability
- pressurized living area
- cabins
- Max amount of people
- any other specification that you can think of.
Thanks!!
A BFR development tracker on the everyday astronaut website would be super cool..
good idea. meaybe you can do it
maybe make it a google doc
So you and Elon are like besties now, yeah? :D
Musk being involved in a long-form interview by yourself and Scott Manley would be nerd christmas. Lets make this happen.
great camera and editing work! i'm very impressed with the shots you guys got considering you're not the official spaceX camera crew. keep it up
Thank you Tim for the great reporting you do, Keep up the great work. Getting Humans Off this hunk of rock will take alot of Work.
Maybe Eventually they want to achieve something like Starship Enterprise..!
I guess?
This new BFR reminds me of mid 20th century scifi rocket designs wear the rockets would ALWAYS land on their fins.
Really makes you think, were they onto something?
GREAT Work, INSIGHTFUL Questions, BRILLIANT Energy&Attitude, INSPIRING What your have accomplished !!!
That eye joke was hilarious, major props for that. I like ur videos.
I didn't even know you had different coloured eyes until you said it
Imagine the BFR popping a space station (or several modules) into orbit.
And I don't mean it being carried in the BFS shuttle-style, I mean Skylab-style, where the module is plopped on top of the BFR.
The latest proposed design of the BFR actually has a larger pressurised volume than the ISS (1000m^3 versus 953m^3). It basically is a space station.
If they could modify the design (remove wings, as reentry not needed, have the nose cone pop off or something once aerodynamics are not needed), and dock two of them together, it would create a truly massive space station. And for a fraction of the cost of the ISS.
Furthermore, picture an inflatable station module with the "packed" size being that of the BFR's max fairing capacity.
@@aussie_boosh That could actually work... You should reach out to Elon Musk and suggest that he create the first privately owned/launched space station, and maybe if he could figure out how to dock 4 of them together, he could make the first ever space hotel... and maybe either the station or the hotel could be a checkpoint for BFR's headed to other planets. And this isn't a joke, I mean this seriously.
@@levisabin3047
that'd be sick!
@@levisabin3047, the technology does indeed exist for this to happen. Bigalow Aerospace has an expandable habitat attached to the ISS which was carried into orbit by a Falcon 9. They also have had a couple of units in orbit by themselves.
Love these videos, and love what you do!!
Congrats man! I was so excited when you asked a question to Elon! Very happy for you! Keep up the amazing work!
The Germans were developing this sort of thing back in WW2, rather than re entering the atmosphere at max velocity, going strait down and trying to bleed off speed very quickly, creating a lot of heat and stress on the vehicle, they would sort of dip into the atmosphere and quasi surf, bounce off the atmosphere , using the wings to change the angle once they get some bite.. use that energy to skim along or even ascend a little, burning off speed, and doing this over and over again until going slow enough to enter like the falcon stages do.. Apollo did the same thing when coming in at 24, 000 miles an hour, they used thrusters to change the angle the capsule engaged the atmosphere, at times actually ascending during re entry.. apollo had the advantage of a blunt shape, shock wave that protected the vehicle, but she still got mad hot..
Space X is using this method to the nth degree, and since the vehicle is huge, and not as robust as apollo, those wings will slow the craft even further , providing for a gentler re entry ... the trick will be how they manage energy and heat around the Karman line, and keep it within limits.. It's like skipping a stone on sand paper, until the stone finally slows down to a manageable speed.. The Germans planned a space plane that skipped along the atmosphere after being launched by a bunch of V2 boosters,,
drop bombs on New York, and skip it's way back across the atmosphere around the world back to Germany.. all in like 2hrs..
It was the theoretical work from this program that allowed Nasa to use the same method to get around the high approach speed of lunar trajectories without having to use huge retro rockets to slow it down on approach to earth.. kind of surfed the atmosphere and used it as an aerodynamic brake.. Space X is suing the same method, but to a much greater degree, and with much tighter tolerances as the BFR is less tolerant of heat and friction, probably less so than the space shuttle.. so it will need a gentler , cooler approach..
The theory for this was already done in the 60's with the x15 program ,and "Dynasoar", where aircraft with no heat proofing tiles etc , managed to re enter the atmosphere after crossing the Karman line, all be it at much much lower speeds.. with the Advent of Pica, carbon fiber, titanium alloys, and nomex linings, and very very fast processors that can keep the vehicle on it's intended path , and manipulate those wings precisely and fast enough to maintain the correct attitudes ( a minor mistake at these speeds, even 10th's of a degree error will result in disaster).. the vehicle will either g out, and come apart, or skip off the atmosphere so hard it flies back into space .. having no fuel to re enter again.. just like Apollo.. though Apollo had a far greater margin for error as it was blunt and tough.. no protective shockwave for BFR, no ablative heat shield.. too much weight to make the vehicle viable.. this is going to be a dance with the Devil at the edge of the atmosphere.. with no room for error, very very difficult..very very cool..amazing tech.. good on Space X for tackling it.. the iterations we see in the design must be the result of Space X coming to conclusions about the viability of the size of the vehicle, and how much surface area is needed on those wings and provide a margin of safety.. the earlier lifting body type shapes we saw in 2016, 2017, may not have been proven or didn't stand up to tests in simulation.. I'm guessing the BFR shapes didn't provide enough control in certain critical phases of the decent, or added a lot of thrusters and complexity to the vehicle.. so they decided to go with larger wings.. plenty of fluid dynamic data available from the shuttle, it's proven and it works.. lifting body ? don't know of anybody that's ever done a re entry from orbit with one.. un charted territory, and space x would have to do all the R n D , build and test scale models , then hope it works and a bloody huge vehicle.. so we see it looking more like the shuttle..
I would love to know how this thing will manage heat, and how robust the airframe is , and how they get around issues of weight and complexity.. what it can bring to orbit is all well and good.. how it gets back..now that's interesting.. if Every Day could do a video on how the BFR will perform on re entry, and maybe his thoughts on the BFR's design .. that would be awesome..
I agree - if the context of this comment is your opinion. Long comment. . .
The brand new design just looks a hell of a lot cooler and more science fictiony.
Modern rockets will converge towards a Tin-Tin style of rocket design ;)
I think it looks a bit more natural, almost dolphin like!
Great job Tim!!!
One word to describe this. Inspiring!
